Uppy is an open source project by Transloadit


To keep Uppy lightweight, we’re aiming to carefully select what packages we include. The graph below will help us discover low hanging fruit. Sizes and dependencies shown here are for the bundled version of Uppy, which includes all plugins we offer. In production, when you pick and choose just the ones you need, the size will be much smaller:

  • Drag & Drop + Multipart uploads ≈ 18 Kb mingz
  • Full-featured Dashboard with image previews and progress indicators + tus resumable uploads ≈ 36 Kb mingz

This graph is built with Hugh Kennedy’s excellent disc.

Bundle Sizes

Below are the minified and gzipped sizes for each Uppy package. Note that this includes the dependencies for each package, some of which are shared when you install multiple plugins—for example, the @uppy/dropbox and @uppy/instagram package are both over 11kB including dependencies, but only sum up to about 15kB when they are used together.
